No equipment lock if you’re moving up. 2 years if moving laterally or down. In other words, if you get the 737 or 320 in initial you can go to the 756, 787 or 777 in the next vacancy bid if you wanted to and could hold it. If you get the 756 you can only move up to the 787 or 777. If get the 787 or 777 in initial then you’ll be there for two years or whenever you take an upgrade, whichever comes first.
